FABRIC-COATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 738,347, dated September 8, 1903. Application filed November t, 1902. Serial No. 130,092. (No model.)

To all whom it may concern:

Be it known that 1, JOHN N. MYERS, a citizen of the United States, residing at Wabash, in the county of Wabash and State of Indiana,

have invented certain new and useful Improvementsin Fabric-Coating Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to fabric-coating machines, and has for its object to provide a device of this class which will deposit on one or both sides of the paper or fabric treated a. coating of clay or other material by means of a vapor or spray holding in suspension the substance to form the coating.

A further object of my invention is to simultaneously dry the paper or fabric to such an extent as to make it possible to proceed with the further steps usual in the manufacture of coated paper or fabric with little or no loss or waste of time.

With these objects in view my invention consists in the novel construction of the apparatus hereinafter described.

My invention also consists in certain combinations of parts which will be first fully described and afterwards specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a side elevation of my invention, a portion being broken away to show the construction. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged View showing the vital principle of the device.

Like numerals of reference indicate the same parts throughout the several figures, in which-- 1 indicates a roll of paperor fabric suitably supported on the bottom of the machine.

2 indicates uprights, and 3 indicates feedrolls secured thereto at the bottom thereof. 4: indicates color-boxes secured to said uprights above the feed-rolls, and 5 indicates air or steam pipes located beneath the said colorboxes, said pipes being horizontally arranged and having a longitudinal opening 6 therein their entire length and a lip or projection '7 formed thereby. In the inside walls of the said color-boxes I provide a valve or gate 8 their entirelength, whichis adapted to control the flow of color from the boxes.

9 indicates a stand-pipe placed on the side of the machine, carrying a series of branch pipes 10, which are supported in the uprights '2 in pairs directly opposite each other, said pipes 10 being provided with longitudinal openings their entire length between the uprights and are also movably secured to the rollers, preferably of felt, and to one side thereof are the dry-racks. (Not shown and which form no part of my invention.)

11 indicates a chain which passes fr om the upper to the lower set of feed-rolls for the purpose of having both sets of rolls revolve together and at the same speed. I also show brushes 13, secured at 14; to the uprights be tween the branch pipes 10.

Having thus fully described the several parts of my invention, its operation is as follows: The roll of paperor fabric 1 to be coated is placed as shown in Figs. 1 and 2 and passes between the lower set of feed-rolls, which are revolved by any suitable power. The paper or fabric thence passes up between the colorboxes and the series of hot-air or steam pipes 10 and between the upper 'set of feed-rolls.

The paper or fabric having been thus started the hot air or steam is allowed to issue from the pipes 10 and from the pipes below the color-boxes. The color in said boxes runs down upon the lips of the air or steam pipes below, and the sheet of air or steam from said pipes sprays it on the fabric or paper. The amount of color sprayed is controlled by the gates or valves in the color-boxes. It is obvious that only one side of the paper or fabric may be coated, and in this event I have found it advisable to spray the other side with water to prevent curling. The paper or fabric as it is being coated is being carried up and passes between the hot-air or steam jetting pipes 10, which are so arranged in position and numbers that the paper or fabric is in a condition to pass between the upper feedrolls and onto the dry-racks without being injuredin any way. As is obvious, both sides of the paper may be coated at the same time or only one side, if desired, and the color-boxes may be duplicated on one or both sides of' the paper in order to double-coat the same. As before stated, the hot-air or steam pipes 10 are movable or adjustably secured to the main stand-pipe, so that the angle of the jet-s of steam or hot air striking the paper or fabric can be regulated, so as to assist in carrying the paper upwardly between the jets. This is a material feature of my invention, as the fiber of. the paper or fabric is somewhat weakened after passing between the coating-spray and while yet wet might possibly be damaged by the pull of the feed-rolls. The impact of the hot air or steam at an upward angle dries the paper or fabric and at the same time assists in raising the same to such an extent that the fiber is not damaged in the slightest degree.

Having thus fully described my invention, I do not wish to be understood as limiting myself to the exact construction as herein set forth, as various slight changes may be made therein by those skilled in the art which would fall within the scope of my invention, and I consider myself clearly entitled to all such changes and modifications.

What I claim as new, and desire to secure by Letters Patent of the. United States, is

1. Ina fabric-coating machine the combination with the coating means, of a series of pipes located above said coating means and provided with longitudinal openings the entire width of the fabric and adapted to jet hot air or steam against the fabric to dry the same and means for brushing the fabric.

2. In a fabric-coating machine, the combination with the coating means of a series of pipes located above said coating means, and adapted to jet hot air or steam against the fabric to dry and raise the same and means for brushing the fabric.

3. In a fabric-coating machine, the combination with a coating means, of a valve for regulating the same, a series of pipes located above said coating means adapted to jet hot air or steam against the fabric.

4. In a fabric-coating machine, the combination with a coating means of a valve therein for regulating the same, means for forcing a jet of steam or hot air against the fabric to dry. and raise the same.

5. In a fabric-coating machine, the combination with a coating means of means for jetting hot air or steam against the fabric to dry and raise the same and means for brushing the fabric.

6. In a-fabric-coating machine, the combination with a coating means, of means for jetting hot air or steam against the fabric to dry and raise the same, and means for adjusting the angle of impact of said hot air or steam and means for brushing the fabric.

7. In a fabric-coating machine, the combination with a coating means, of means for spraying the fabric on the opposite side from that coated, and means for jetting hot air or steam against the fabric and dry the same.

8. In a fabric-coating machine, the combination with feed-rolls, of a coating means above said feed-rolls, means for jetting hot airor steam against the fabric, and feed-rolls above said jetting means.

9. In a fabric-coating machine, the combination of acolor-box, a pipe below said box provided with a longitudinal opening therein, a lip on said pipe formed by said opening to catch the color.

10. In a fabric-coating machine, thecombination of a color-box, a pipe below said box having a longitudinal opening therein, a lip formed on said pipe by said opening, and means in said color-box for regulating the flow of color therefrom.

11. In a fabric-coating machine, the combination with a coating means, of a hot-air or steam stand-pipe, a series of smaller pipes leading therefrom and movably secured thereto, and provided with longitudinal openings the width of the fabric, and adapted to jet the fabric with hot air or steam.

12. In a fabric-coating machine, the combination with the feed-rolls, of means for coating the fabric on both sides, means for brushing the same, means for regulating the flow of the coating material, and means for drying the fabric.

13. In a fabric-coating machine, the combination with the feed-rolls, of means for coating the fabric, means for regulating the flow of coating material, and brushes arranged for
